Shared secrets do not survive modern banking

Real time payments, open banking, and AI driven systems have reshaped financial infrastructure, yet many services still rely on portable API keys and long lived secrets. Smallstep replaces them with short lived, hardware bound certificates that prove service identity and reduce third party and regulatory risk.

Identity Risk in Modern Financial Systems

Integrations icon

Autonomous financial systems

Fraud engines, settlement services, liquidity systems, and partner integrations operate continuously without human interaction.

Cross-platform coverage

Regulatory scrutiny

Examiners increasingly demand clear evidence of service level access control, provenance, and third party governance.

Certificate icon

No cryptographic proof

Shared secrets cannot prove which workload initiated a transaction or accessed regulated customer data.

Third party concentration risk

Open banking and embedded finance expand partner connectivity while increasing systemic exposure.

MDM integration icon

Lateral movement

Compromised credentials allow silent pivoting across APIs, data stores, and core banking platforms.

Devices icon

Board level accountability

Operational failures and data incidents translate into capital impact, reputational damage, and executive liability.

Hardware-backed device certificates

Identity With Verifiable Provenance

Smallstep anchors service identity in hardware and issues short lived certificates only to verified workloads. Every connection is backed by cryptographic proof that stands up to audit and incident response review. Replay risk, credential reuse, and secret sprawl are structurally eliminated rather than administratively managed.

Device Identity Platform

A Control Plane for Non Human Access

Centralize policy for internal services, partner APIs, AI systems, and automation pipelines. Define access once and enforce it consistently across cloud, on prem, and hybrid environments. Replace fragmented secret distribution with governed certificate lifecycle and measurable controls aligned to regulatory expectations.

Zero Trust Built for Financial Throughput

Enforce continuous authentication without slowing transaction flow or customer experience. Decisions are based on verified workload identity and policy, not static login events. Security, platform engineering, and compliance operate from the same source of truth.

Meets Financial Services Security & Regulatory Expectations

Smallstep supports alignment with PCI DSS, FFIEC guidance, GLBA, SOX, ISO 27001, SOC 2, NIST CSF, and Open Banking standards.

By replacing shared secrets with short-lived, hardware-bound certificates, it strengthens cryptographic authentication, audit defensibility, and least-privilege access across payment systems, APIs, and cloud infrastructure.

API keys are incompatible with systemic financial risk

Portable shared secrets were designed for simple systems, not interconnected financial networks. In regulated environments where every transaction must be attributable and defensible, API keys create unbounded blast radius, weak audit trails, and unmanaged third party exposure. Financial infrastructure requires identity that is provable, constrained, and continuously verified.

Built for CISO, Platform Engineering, and Compliance

CISOs gain measurable reduction in third party and non human access risk. Platform teams gain automated certificate issuance and simplified infrastructure operations. Compliance leaders gain verifiable evidence that withstands examination. One identity architecture that aligns security posture, operational resilience, and regulatory accountability.

Identity Is Now a Board Level Control

As financial systems become autonomous and interconnected, identity defines your true security boundary. Replace shared secrets with verifiable service identity, enforce policy across every integration, and build an architecture that survives regulatory examination and systemic scale.
